The holy book of Jewish mystics. Correct spellings seem to be those matching /{KQ}abal(l)?a(h)?/. (Replace curly braces with square brackets.) Of course, it's really spelled koof-bet-lamed-hay, but my computer isn't set up to type in Hebrew. Composed of two parts: the Book of Creation (Sefer ha'Briat) and the Zohar.

A Jewish mystical belief system claimed to have been practiced since God spoke to the Patriarchs but which historically gained significant popularity sometime before the 10th century AD. It is based on the belief that God is actually not a transcendant being but was itself created and made Creation through the emanations of a higher, transcendant power called the Ain Soph or Eyn Soph (transliteration varies). These emanations took the form of the Tree of Life (Etz Chayim).

One of the reasons that the Jewish people do not believe Jesus was the son of God. In Qabalah, each letter in the Hebrew alphabet has a different number associated with it (which changes according to context, etc.), so that words can have values ascribed to them. The name of the serpent in the Garden of Eden and Jesus have the same value, and therefore are the same entity.
